I need to add a new radiator to my house (hallway has none and it's
cold!)

I plan to tap into the CH Flow and Return pipes which already run
underneath there, and plan to use solder ring connections.

My question is this, the access panel for my crawl space is at the
opposite side of the house, so I have to go down beneath the floor and
haul myself along through the rubble to the place where the pipes will
go.

How safe is it to use a blow torch in this confined space? (About 18
inches of verticle space benathe the floors). Apart from the obvious
need to not set the house on fire, I'm more interested in the fumes
given off by the blow lamp. What can I do about those?


You will be fine. As long as its not hermetically sealed. You will
produce fumes faster than a few soldered joints with a torch will.

Anyway teh first signs of anoxia and CO2 overdose is feeling dizzy and
headachy, so just watch out for feeling rough, and if you do, break for
a cuppa.

In fact, do that anyway. wortkng in 15" of rubble infested space you
will need it.

Or if really paranoid use a fan. Coal miners work in less than 15"
sometimes. Forced air keeps them alive.




I'd rather not use 'speedfix' or compression if I can avoid it, just
for peice of mind.


Peace of mind? Or a piece of my mind?
